Abstract

The lifting clamp has a annular body (1) and lifting lug (8). The clamping means is provided by jaws (7) sliding in angled guides (6) which are integral with the body. The jaws are connected by rods (9) to an axially movable ring (10). Cylinders (11) are situated between the jaws which move the ring to a lowered position, and thereby slide the jaws in the angled guides until they grip the outer surface of the object to be lifted.
